7 Claims.

This invention relates to a bracelet construction and more particularly to a buckle characterized by a plurality of folding links or the like.

One of the objects of this invention is to provide a buckle which will be simple, practical and thoroughly durable. Another object is to provide a device of the above character which may be manufactured from inexpensive materials at low labor cost. Another object is to provide a device of the above character in which the operating parts may be easily assembled and in which the completed article is attractive in appearance. Another object is to provide a buckle of the above character capable of quick release to give a maximum dimension Ito the bracelet while still eiecting a very minute adjustment of the length thereof when so desired. Another object is to provide a device of the above character having a fingerpiece in a readily accessible positionfor operation. Another object is to provide a device of the above character in which the various operating parts work with extreme ease so that changes in the length of the bracelet may be conveniently effected. Other objects Will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts as will be exemplified in the structure to be hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible embodiments of this invention,

Figure 1 is a top plan View of my buckle with the links thereof in unfolded position;

Figure 2 is a bottom plan view of the buckle shown in Figure l;

Figure 3 is a bottom plan view of my buckle with the links in folded position;

Figure 4 is a vertical sectional view taken along the line 4-4 of Figure 3, on an enlarged scale;

Figure 5 is a vertical sectional View taken along the line 5-5 of Figure 2;

Figure 6 is a lo-ngitudinal vertical sectional view taken along the line E--Ii of Figure 2, and

Figure 7 is a horizontal sectional view of the parts shown in Figure 6.

Similar reference characters refer to similar parts throughout the several views of the drawing.

To afforda clearer understanding of several of thefeatures of this invention, somecfzthe didiculties encountered in buckles of this general charac-ter now in use will be described. Some of these buckles have no release for the pawl and ratchet when the links are in folded position and accordingly if the wearer decides to increase the length of the bracelet it is necessary to unfold the links, resulting in inconvenience. Other buckles of this general character are provided with actuating apparatus such as flngerpieces so located that it is extremely diilicult to operate them when the bracelet is in position on the wrist of the wearer. Furthermore, many of these buckles are so complex in structure that it is very diflicult to make the parts in proper dimensions, and the problem of assembly thereof is also difficult. Thel construction of many of these buckles is such that use thereof creates considerable Wear and tear on the moving parts resulting in a short life. One o-f the objects of this invention is to provide a device for overcoming these difculties as well as many others.

Referring to Figure 1, my buckle comprises a housing link generally indicated at I Within which is slidably mounted a sliding link generally indicated at II. Preferably sliding link II is secured to one end I2 of a bracelet generally indicated at I3 (only partially shown). Although end I2 of the bracelet may be secured to the sliding link in any convenient manner, I prefer to provide a slot I 4 adjacent the end of sliding link II and a collar I extending through the slot and fitting about a cross-piece I6 of the end of the bracelet.

A link generally indicated at I'I is hingedly connected to housing link IU in a manner to be described more fully hereinafter, and a link generally indicated at I8 is slidably mounted within link I'I. Hingedly connected to link I8 is a link generally indicated at I9 having its end secured to the other end 2i] of the bracelet I3. Preferably link I9 is connected to end 2D by an eye portion 2I iitting about the crosspiece 22 of the end link.

Referring more particularly to Figures 2 and 4, housing link l) preferably comprises a top portion 23, longitudinal side Walls 24 and 25, and inwardly extending ange portions 26 and 21 spaced below topportion 23, as best seen in Figure 4. Thus the opposite sides of housing link IU take the form of longitudinal channels 28 and 29, channel 28 being bordered by top portion 23, side Wall 24 and iiange portion 26, while channel 29 is bordered by top portion 23, side Wall 25 and flange portion 21.

Still referring to Figure 4, the section of top portion 23 substantially disposed between channels 28 and 29 is bent outwardly to form a longitudinal depression 39 within the housing link. As best shown in Figures 4 and 5, a movable part generally indicated at 3i is disposed within ridge 30 and is pivotally connected at the end of housing link I adjacent link I1. Thus part 3l has a pair of ears 32 and 33 (Figure 5) adjacent side walls 24 and 25, and an eye portion 34 on link I1 (Figure 2) bridges the space therebetween. Thus the ends of eye portion 34 as well as ears 32 and'33 t underneath ilange portions 26 and 21. A pin 35 extends through ears 32 and 33 and eye portion 35, and is preferably headed over on side Walls 24 and 25. Accordingly pin 35 not only serves to hingedly connect link I1 to housing link ID but also it secures part 3I within housing link I9 so that it is free to pivot in directions toward and away from top portion 23.

The central portion of part 3I is cut away to form a longitudinal slot 36, as best shown in Figures 2 and '1, while the end portion of part 3| opposite pin 35 has secured thereto a pawl or catch part 31. Preferably catch part 31 is an upturned cut out portion of part 3| as best shown in Figure 6. The end of part 3I is preferably bent over upon itself to form an eye portion 38 (Figure 6) located immediately adjacent the end of housing link I0. Preferably top portion 23 of the housing link is cut out forming an indentation 39 (Figure l) within which. fingerpiece 38 rests.

Referring now to Figures 4 `and 7, sliding link I I -rests on top of part 3I as viewed in Figure '1.

` any attempt is made to move the sliding link in The sides of slidingl link II are bent upwardly and inwardly to formi ridge portions 49 and 4I fitting within channels 28 and 29 respectively (Figure 4). The dimensions of the sliding link are such Ithat the sides of ridge portions 40 and 4I substantially engage sidewalls 24 and 25, whereas the depth of the ridge portions is much less than the depth of channels 28 and 29. Thus there is. a substantial space between the inside surface of top portion 23 and the bottom surface of sliding link II as viewed in Figure 2. Accordingly part 3| is free to pivot about pin 35 between sliding link II and top portion 23 for a purpose to be i more fully described hereinafter.

Formed along the central portion of sliding link II is a series of slots forming teeth generally indicated at 42. Teeth 42 are in line with pawl member 31 and consequently longitudinal movement of the sliding link with respect to the housing link results in an engagement of the pawl member with the several teeth. However, as best shown in Figure 6, pawl member 31 presents a sloping surface to the teeth when the sliding link is moved inwardly and an abrupt surface when the opposite direction. Accordingly the sliding link may move vinwardly as the teeth will ride over the pawl member. But when part 3I is in its normal position, longitudinal movement of the sliding link in an outward or extended direction is prevented by engagement of one of the teeth wit-hthe abrupt side of pawl member 31. Should the wearer desire to move the sliding link outwardly to extend the bracelet, it is merely necessary to move part 3l against the top of the housing link by way of iingerpiece 38 to disengage pawl member 31 from. the teeth. Preferably the inside end of sliding link I I has a lip 43 extending into slot 36 (Figure 2) to serve as a guide during the llongitudinal movement of the sliding link within the housing link and also to serve as a stop when the sliding link is in its outermost position.

Links I1, I8 and I9 may be of any' desired construction to it within housing link I8 between flange portions 2S and 21 (Figure 2). Preferably link I1 is channel shaped in cross section having inwardly extending flanges 44 and 45 and a pair of ears 48a. and 4Gb bridging the end thereof to form a slot 41. Link I8 is slidably mounted within link I1 and has an upturned lip 48 disposed within slot 41 and shaped to engage ears 49a and 4Gb when link I8 is in extended position. Thus link I8-is free to slide in link I1 within the limits of the length of slot 41- Links I8 and I9 are pivotally connected and link I9 is channel shaped in cross section having side walls 49 and 59 extending upwardly as viewed in Figure 1. Walls 49 and 50 are pro vided with longitudinal projections I and 52 (Figures 1 and 4) for a purpose to be described hereinafter.

As shown in Figure 4, flanges 28 and 21 and top portion 23 of housing link II) form an elongated channel Within link I9 in which sliding link II slides. Link II is spaced inwardly to- `ward top portion 23 from flanges 2S and 21 to provide a nesting space for folding links' I1,

I8 and I9 in housing link I9 regardless of the longitudinal position of sliding link II therein.

As shown in Figure 6, my buckle is curved and .much longer than it is thick, to provide ample extensibility and yet permit the buckle to lie iiat against and conform to the wrist and preclude unsightliness and interference with the sleeve.

When the wearer desires to fold links I1, I8 and I9 into the nested position shown in Figures 3 and 4, link I8 rst slides into link I1 while link I1 is pivoting about pin 35 (Figure 2) and link I9 is pivoting about its hinge connection 53 with link I8. Finally link I1, with `link I8 disposed therein, rests between the flange portions 26 and 21 of the housing link and side walls 49 and 50 are disposed between the sides of link I1 vand the flange portions of the housing link. Flange portions 28 and 21 are so proportioned that when links I1, I8 and I9 are so folded into the housing link, longitudinal projections 5I and 52 snap over the inner edges thereof to retain the links in this position. However the links may be conveniently released by pulling link I9 upwardly, as viewed in Figure 3, this being best accomplished by inserting the fingernail beneath a projection 54 extending frorn the end thereof.

Referring to Figure 4, it will now be seen that when links I1, I8 and I9 are in the closed or nested position, they are sufciently spaced above sliding link 29 so that this member is free to slide into extended and contracted positions without hindrance. In normal use the bracelet, with my unique bucklese'cured thereto, is first slipped over the hand of the wearer while the buckle is in the extended position shown in Figures 1 and 2. Next links I1, I8 and I9 are moved into the nested position after which the wearer may get a ne adjustment of the length of the bracelet by moving the sliding link II in either direction` If the wearer desires to shorten the bracelet, it is merely necessary to move the sliding link further into the housing link as the teeth 42 (Figure 6) will ride over pawl member 31. However if the` wearer desires to lengthen the bracelet slightly, he can do so by placing his fingernail beneath the ngerpiece 38 and pulling it upwardly as .viewed in Figure l. rIhis moves pawl member 31 out of engagement with the teeth so that the sliding link is free to move outwardly with respect to the housing link.

It will thus be seen that my buckle offers a great variation. in the adjustment of the length of a bracelet. Furthermore, regardless of the position of the folding links, the sliding link remains in any desired position until changed by the wearer. If the wearer desires to make a fine adjustment of the length of the bracelet this may be done by actuating the ngerpiece, and it is to be particularly noted that the ngerpiece is in a very accessible position where it may be con.- vcniently operated. Furthermore, the various partsl of my buckle are simple in construction, thus being easily manufactured and assembled.

Accordingly I have provided a thoroughly practical and efficient construction in which the several objects hereinabove mentioned are accomplished and in which the diiculties herein referred to as well as many others are successfully eliminated.

As many possible embodiments may be made of the above invention, and as many changes might be made in the embodiment above set forth, it is to be` understood that all matter hereinbefore set forth or shown. in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
